Arden 09 glow flat hex head
David Norrid:
My next project is for a Forster 29 I got in a junk lot. I know it will start. Lots of compression.

When I tested the engine all I had was a 7 x 6 prop to put on it which is pretty steep for that engine. It was turning around 6500 rpm with 5% nitro and 28% castor oil. It is very loud but I live in the sticks so it doesn’t matter. Thanks

For a prop, I wouldn't go much more than 5" pitch, and 7 to 8 inch diameter. When you get to the Forster, they are pretty similar to a Fox .29, maybe a bit less power. It will inform the neighbors in the next county that it is running also!!
Have fun,
Dan McEntee

David: I have quite a few Arden engine but I've never seen that head configuration.
They did indeed make a number of configurations as seen in the photo.
From top left clockwise:
1) .099 with tank, spark ignition
2) .099 glow, no tank
3) .099 glow with tank
(All .099s are plain bearing)
4) .199 missing tank, spark ignition, ball bearing.
All these are magnesium but somewhere I have one cast in aluminum.
I plan to build another Wee Duper Zilch and power it with engine number 2.

That is cool. The second engine is almost the same. Yours has that little tube on the venturi which mine could have had and someone removed it. Mine ran fine without it. Mine has that funny head as you mentioned and I did lots of research and found alot of pictures but never saw a head like mine. Thats why I was thinking it was maybe home made as it is fairly crude being a big hex "nut" with a hole in the middle. Although its not an old design, I decided to build a buster like sig made. I wanted a solid wood wing and that airplane fits the 09. I will post when I get it done. My work is nothing like some of these guys can do but I am not a patient man and when it gets down to the end finishing I just seem to want the model off my work table. You should post yours too. Thanks for your input.
Robert Zambelli:
David - let's see some photos of your Forster 29.
They made a number of versions of it.
I can post some photos of mine if you wish.
